Application of Computer Virtual Reality Technology in Design

With the continuous development of technology, the design of the environment can be simulated by computer technology. The virtual reality (VR) technology can be used to take the real world as a three-dimensional space, three-dimensional space can be designed to simulate the actual environment. In this paper, virtual reality technology is applied to design, and design is divided into two fields, namely landscape design and scene lighting rendering. We study characteristics of virtual reality technology and framework of virtual reality technology, at the same time, we define the concept of light and the concept of landscape in design, and analyze the problem of lighting rendering and the problem of landscape design. From the perspective of landscape design, we discuss the difficulties of virtual reality-landscape design, and further analyze the landscape design level and multi environment elements display based on virtual reality technology, and propose a feasible virtual reality-landscape design method; from the perspective of light rendering, the principle of lighting tracking algorithm can be analysised, the realized method is used for lighting rendering, the game engine is used as the rendering engine, MAYA and Photoshop software are used as the main rendering techniques of virtual reality, therefore, the real-time rendering of landscape's surrounding environment is realized.
